Yamaha ActiveTune AFR closed-loop self-tuning ECU kit (YEC)


PLEASE NOTE: This kit is intended for the YEC Race kit wire harness; if you are using the stock Yamaha harness, please click here to view the stock Yamaha harness variant of this kit.

This Kit lets your FTECU-equipped bike tune itself as you ride!

Once installed and activated, the ActiveTune kit monitors the fuel mixture, making fast and consistent changes to meet different air/fuel requirements.

Our breakthrough system replaces your inadequate stock O2 sensor with a proprietary FTECU lambda controller and the latest generation Bosch LSU 4.9 sensor.
